What is the intended purpose of using slope drains in stormwater management?

The intended purpose of using slope drains in stormwater management is to convey runoff safely down cut and fill slopes. Slope drains are specifically designed to manage and guide stormwater runoff from higher to lower elevations, especially in areas susceptible to erosion due to grading or construction activities. By doing so, they help mitigate the risk of soil erosion and sediment displacement by channeling water away in a controlled manner. This not only protects the integrity of the slopes but also aids in reducing the potential for flooding or water pooling in undesired areas.

While diverting water away from buildings is a crucial aspect of stormwater management, slope drains are primarily focused on the safe transportation of water along slopes, rather than the broader scope of managing water around structures. Similarly, enhancing sedimentation contrasts with the goal of slope drains, which is to minimize sediment loss rather than promote it. The reduction of soil erosion and management of water flow are critical underpinnings of effective stormwater practices.
